Problems after an update

The web interface of Zeiterfassung is an application that is loaded completely into your browser. So that it does not have to be transferred again on every visit, the browser keeps its program files in a cache.

After an update your browser may mix old and new program parts — it takes some of them from the cache and loads the rest freshly from the server. The result are errors that only happen to you and that disappear once the cache has been cleared.

Your time data is not affected

The cache holds program files only — layout, icons, the code of the interface. All bookings, times, Fehlzeiten and Stammdaten live on the server. Clearing the cache does not lose a single booking.

Typical symptoms

What you see	What is behind it
The page stays on the loading screen (three bouncing dots)	A program file from the cache no longer matches the new version.
A white or empty page after signing in	Same as above — the application aborts while starting.
The bar „Unerwarteter Fehler aufgetreten …” appears at the bottom	The application ran into an error. The Aktualisieren (refresh) link in that bar is always the first thing to try.
Screens look shifted, icons are missing or show up as boxes	Old layout or font files from the cache.
The new features announced with the update are missing	You are still looking at the old version from the cache.
Actions fail although your input is correct	The old interface is talking to an already updated server.

First check whether it really is your browser

If colleagues see the error as well, it is not a cache problem. Report it to your administration or to support instead — the steps on this page will not help in that case.

Step 1: Reload the page completely

A normal reload (F5) still uses the cache. You need a full reload that bypasses it:

System	Shortcut
Windows — Chrome, Edge, Firefox	Ctrl + F5 or Ctrl + Shift + R
macOS — Chrome, Edge, Firefox	⌘ + Shift + R
macOS — Safari	⌘ + ⌥ + R

Press the shortcut two or three times in a row and wait each time until the page has finished loading. In many cases that already settles it.

Step 2: Close the browser completely

If step 1 does not help, close all windows and tabs of the browser — not just the tab with Zeiterfassung — and start it again. Only then is the background service stopped that serves the application from its stored files. Open Zeiterfassung again afterwards.

Step 3: Delete the site data for Zeiterfassung

If the error persists, delete the stored data for this one website. That is more thorough than step 1 and leaves every other website untouched.

This signs you out

The site data also holds your session and small local settings — such as the Mandant number you last used and remembered filter settings. Have your Benutzername, password and Mandant at hand before you continue. The next visit takes longer again, because the application is downloaded from scratch.

Chrome and Edge

1. Open Zeiterfassung.

2. In the address bar, click the icon to the left of the address (padlock or slider icon, “Site information” / „Website-Informationen”).

3. Choose Cookies and site data („Cookies und Websitedaten”).

4. Delete the stored data — depending on the version the entry is called Manage and delete site data, Delete data or is a bin icon. Confirm the prompt.

5. Close the browser completely, start it again and sign in.

Firefox

1. Open Zeiterfassung.

2. Click the padlock icon in the address bar.

3. Choose Clear cookies and site data… („Cookies und Website-Daten löschen…”) and confirm.

4. Close the browser completely, start it again and sign in.

Safari (macOS)

1. Open Safari › Settings › Privacy.

2. Click Manage Website Data….

3. Find the entry for the address of your Zeiterfassung, select it and click Remove.

4. Quit Safari completely, start it again and sign in.

Deleting all browsing data (last resort)

If you cannot find the way via the address bar, Ctrl + Shift + Del (macOS: ⌘ + Shift + Del) opens the dialog for deleting browsing data in Chrome, Edge and Firefox.

1. Choose All time as the time range.

2. Tick Cached images and files — and, if the error remains afterwards, Cookies and other site data as well.

3. Confirm with Delete data.

Caution

This affects all websites: you are signed out everywhere you were signed in. Only take this route once the targeted one above has failed.

Phone and tablet

Device	What to do
iPhone / iPad (Safari)	Settings › Safari › Advanced › Website Data, swipe the entry for your Zeiterfassung to the left and delete it.
Android (Chrome)	Open Zeiterfassung, tap the icon left of the address in the address bar › Cookies and site data › delete.
Installed on the home screen	Android: Settings › Apps › Zeiterfassung › Storage › Clear cache. iOS: remove the icon from the home screen, delete the Safari website data as above, open the page again and add it to the home screen once more.

Windows client and mobile app

The steps on this page apply to the web interface in the browser only.

• The Windows client (Desktop / Verwaltung) has no browser cache. If it shows errors after an update, install the current version again from the download page.
• For the mobile app, close the app completely (swipe it away in the app switcher) and start it again. If the error remains, update the app in the App Store or on Google Play — see Downloads & installation.

If nothing helps

Contact your administration or support. The following details speed things up considerably:

• What you were trying to do and when (date and time).
• Which browser in which version, on which device.
• A screenshot of the error message or of the empty page.
• Whether the error happens to others as well, and whether it also happens in a private window (incognito mode) — a private window uses no cache and therefore separates a cache problem cleanly from a real defect.

The error message from the developer console

If you are technically minded: F12 opens the developer tools, the Console tab shows the actual error message. A screenshot of it helps support the most.
